This involves a large amount of change in test scene setup code to allow test scenes to share shared modules
SetupScene is now an instance method that requires an instantiation of SceneHelpers, though other SceneHelpers methods are still static
May split these out into separate classes in the future.
These behave identically to llAttachToAvatar() and llDetachFromAvatar() except that they do not enforce the PERMISSION_ATTACH check
Intended for use in completely controlled dedicated environments where these checks are more a UI hinderance than a help.
Threat level high.
However, at some point it would be far more convenient to receive the TaskInventoryItem in the constructor rather than just the item UUID, so we don't have to constantly refetch our self item.
This is to deal with the hundred lines of command splurge when one previously typed "help"
Modelled somewhat on the mysql console
One can still type help <command> to get per command help at any point.
Categories capitalized to avoid conflict with the all-lowercase commands (except for commander system, as of yet).
Does not affect command parsing or any other aspects of the console apart from the help system.
Backwards compatible with existing modules.
The previous lines-per-second measurement used for top scripts report was inaccurate, since lines executed does not reflect time taken to execute.
Also, every fetch of the report would reset all the numbers limiting its usefulness and we weren't even guaranteed to see the top 100.
The actual measurement value should be script execution time per frame but XEngine does not work this way.
Therefore, we use actual script execution time scaled by the measurement period and an idealised frame time.
This is still not ideal but gives reasonable results and allows scripts to be compared.
This commit moves script execution time calculations from SceneGraph into IScriptModule implementations.
The first llDie() could lock Scene.m_deleting_scene_object.
The second llDie() would then wait at this lock.
The first llDie() would go on to remove the second script but always abort it since the second script's WorkItem would not go away.
Easiest solution here is to remove the m_deleting_scene_object since it's no longer justified - we no longer lock m_parts but take a copy instead.
This also requires an adjustment in XEngine.OnRemoveScript not to use instance.ObjectID instead when firing the OnObjectRemoved event.
This seems to be a particular problem with ReaderWriterLockSlim, though other locks can be affected as well.
It has been seen to happen when llDie() is called in a linkset running more than one script.
Alleviation here means supplying a ScriptInstance.Stop() timeout of 1000ms rather than 0ms, to give events a chance to complete.
Also, we check the IsRunning status at the top of the ScriptInstance.EventProcessor() so that another event doesn't start in the mean time.
Ultimately, a better solution may have to be found since a long-running event would still exceed the timeout and be aborted.
They were all failing assertions but the exceptions these threw were caught as expected Exceptions.
I don't think we can easily distinguish these from the Exceptions that we're expecting.
So for now we'll do some messy manually checking with boolean setting instead.
This patch also corrects the assertions themselves.
This is already being done in the other place where a sensor is added.
Adding a sensor whilst another thread is iterating over the sensor list can cause a concurrency exception.
On the first frame, all startup scene objects are added to the physics scene.
This can cause a considerable delay, so we don't start raising the alarm on scene loop timeouts until the second frame.
This commit also slightly changes the behaviour of timeout reporting.
Previously, a report was made for the very first timed out thread, ignoring all others until the next watchdog check.
Instead, we now report every timed out thread, though we still only do this once no matter how long the timeout.
The Path.GetDirectoryName call in Compiler.CompileFromDotNetText is unnecessary since AppDomain.CurrentDomain.BaseDirectory is always a directory.
Later path concatenation is already done by Path.Combine() which handles any trailing slash.
Removing Path.GetDirectoryName() will not affect the runtime but allows NUnit to work since it doesn't add a trailing slash to AppDomain.CurrentDomain.BaseDirectory.
This allows NPCs to be sensed as agents by LSL sensors rather than as a specific NPC type (which is currently an OpenSimulator-only extension).
Wiki doc on this and other recent NPC functions will follow soon
llGetOwnerKey() could also be extended but this does not allow one to distinguish between an unowned NPC and some other result (e.g. 'no such object' if NULL_KEY is the return.
Also, any future extensions to LSL functions by Linden Lab are unpredictable and OpenSim-specific extensions could clash.
The osGetGrid**** functions will now get the grid settings from the GridInfoService. Set the GridInfoURI in your ./bin/config-include/GridCommon.ini [GridInfo] section.
no need for these checks just use Allow_osTeleportAgent = PARCEL_OWNER
also increased function to severe threat level to make it harder to
accidently enable it for everyone.
Doing this in every script is unnecessary since the event trigger is parameterized by the item id.
All that would happen is 2000 scripts would trigger 1999 unnecessary calls, and a large number of initialized scripts may eventually trigger a StackOverflowException.
Registration moved to UrlModule so that the handler is registered for all script engine implementations.
This required moving the OnScriptRemoved and OnObjectRemoved events (only used by UrlModule in core) from IScriptEngine to IScriptModule to avoid circular references.
An owned NPC is one that only the original creator can manipulate and delete.
An unowned NPC is one that anybody with access to the osNpc* methods and knowledge of the avatar id can manipulate.
This is to correct an oversight I made in the original reimplementation where I mistakenly assumed that avatar IDs could be treated as private.
I am not anticipating that many people were deliberately making use of unowned npcs due to their insecure nature.
If you do need an unowned NPC please call the new overloaded osCreateNpc() function with the option OS_NPC_NOT_OWNED.
This will be documented soon. Options can currently be
OS_NPC_CREATE_OWNED - creates a 'creator owned' avatar that will only respond to osNpc* functions made by scripts owned by the npc creator
OS_NPC_NOT_OWNED - creates an avatar which will respond to any osNpc* functions that a caller has permission to make (through the usual OSSL permission mechanisms).
options is being added to provide better scope for future extensibility without having to add more functions
The original non-options osNpcCreate() function will continue to exist.
The original function suffered from unexpected results due to rounding
errors. An error of only 1 or 2 ulps would cause the code to not detect
a singularity at Y rotation +/- PI/2 and take the non-singularity code
path. The replacement code does not suffer from wildly inaccurate
results at the +/- PI/2 singularity. The check in the code for the
singularity isn't strictly needed, but gives more consistent results
At the singularity, the X and Z rotations add. The if check simply
forces the X rotation to be zero so the entirety of the X+Z rotation is
carried by Z.
Additionally, the test code has been updated to include test cases that
caused the old code to fail. The test algorithm is also updated to
perform a more meaningful test. The original code checked if the values
against expected values. This could fail at +/- PI rotations since a
rotation around an axis by PI causes the identical effect as a rotation
by -PI. The new test code checks that the returned angles can be used
to recreate a quaternion that causes the same rotation.
osParseJSON uses hand-crafted decoding that has two issues
* does not seem to handle top-level JSON lists
* does not seem to handle unicode text
